DHT cannot be removed from the body. It can also be suppressed with treatment. You are suffering from androgenic alopecia which is also called as pattern baldness. The hairs start reducing in density at the crown (top) and also the hairline starts receeding  from the front. This is usually progressive throughout life unless treated. It is usually accompanied by severe dandruff which we call seborrhoea. The FDA approved treatment for this condition is the best. No oil or cream will magically work because the hairs are getting miniaturised  and eventually disappearing due to the hormonal effects of DHT on the hair roots.

I havent come across any scientific research on the same. Also - i am sorry that i am not really familiar with the kind of therapy that you are talking about. But please note - its not that one can " remove " DHT from the scalp or body. Its just that - its synthesis from its precursor - testosterone has to be reduced in order to reverse andro genetic alopecia. KINDLY SEE A QUALIFIED DERMATOLOGIST NEAR YOU FOR DETAILED EVALUATION AND TREATMENT OF YOU HAIR LOSS. SEVERAL SCIENTIFIC TREATMENT OPTIONS EXIST.
